The current code Gitk will use non-blocking mode on the pipes to/from the git-diff-tree process, so there isn't a possibility of deadlock that I can see. > seems to feed a pre-generated list with "open | cmd <<" > construct to the command, so perhaps you are planning to change > that? That's for the "Find" function. I'm in the process of adding the code to let users enter a list of paths and have gitk highlight the commits affecting those paths. That will involve a separate invocation of git-diff-tree. To make it responsive, I'm only going to ask git-diff-tree about the commits that are visible on the screen - but I need git-diff-tree to give me an answer quickly, i.e. in less time than a human can perceive.
